Cingulate sulcus

The cingulate sulcus is a curved sulcus found on the medial surface of the cerebral hemisphere. It surrounds the C-shaped curve of the cingulate gyrus, separating it from the adjacent medial frontal gyrus and the paracentral lobule. Towards the rear, the cingulate sulcus arches upwards behind the paracentral lobule as the marginal branch of cingulate sulcus. This marginal branch serves as a boundary between the paracentral lobule in the front and the precuneus at the back. From this point, the section of the cingulate sulcus that continues around the cingulate gyrus is known as the subparietal sulcus. It separates the posterior part of cingulate gyrus from the precuneus located above it.
